End of MySQL old password support

Posté le vendredi 4 octobre 2019, à 18:08 UTC

MySQL old password support (before MySQL 4.1) backward compatibility is being removed from most MySQL client libraries, at least from the PHP MySQL client library we started using.

MySQL new password support (starting from MySQL 4.1) is quite old, that is, affected databases are those created before 2006 and without a single password change since then, needless to say that only a few of them are affected.

Anyway, we manually renewed a couple of password hash on websites filling a MySQL auth error "The server requested authentication method unknown to the client [mysql_old_password]" in our error log but we can't do much for websites that don't.

Please renew your MySQL database password using the panel if you encounter the issue.
